Magisk: Update on the MagiskHide and Google Pay Issue!

[ghost]

Hi,

I've been looking into this, here's what I did and found out:

A few days after updating to 18.2 Canary I tried enabling in-store payments and Google Pay said the phone was rooted or altered. I then wiped /data/data/com.google.android.gms in recovery, and it worked again for approximately 12 hours (with default MagiskHide settings, only "unstable" enabled in the list). I then wiped data again and enabled MagiskHide on all the Play Services + Google Pay, and it worked for several days, so I considered it to be a pass.

I then disabled MagiskHide on Google Pay and it still worked for several days.

Thus:

• the result of the google pay root check is stored in the /data/data/com.google.android.gms folder (Google Play Services data folder), for all other apps Android just wipes the /data/data folder but that's not the case for Play Services as there's a custom UI for deleting data which doesn't seem to remove everything, and obviously, this data isn't removed. You can wipe /data/data/com.google.android.gms in recovery to remove the result of the check.

• the check is done apparently randomly in the span of a day or two. That's probably to achieve what happened in this thread, conflicting reports and people having no idea what triggers the check and how to deal with it.

• the check is done by Google Play Services, but by something other than the "unstable" (SafetyNet) process.

• not sure about this one, but given that Magisk 18.1 and older have imperfect MagiskHide functionality (the hiding can be "raced" and thus defeated with some tricks, according to John himself), it's possible Google is also doing that. Using 18.2 is your best bet as it enables hiding on a process as soon as possible.

I'm now trying to pinpoint which component of play services is doing the check, so the default MagiskHide list can be updated (I'll report on GitHub once I'm sure).

Reporting that renaming com.google.android.gms to com.google.android.gms.bak worked for me. I was able to successfully add a card where before it was detecting root.

Google Pay had been working before. I set up the phone as new after the May 2019 update. Since then I also can't decrypt the data partition in twrp any longer.

Don't know if and how this all is related to me setting up the phone as new. FYI, Just wanted to share my experiences.
